Can I ask then, on the innovation side, when you talk about.... It's really exciting what you're doing now with the lithium batteries and graphite, and looking at the battery itself, are you working with mining companies to look at other products, like for batteries in heavy equipment?
We've had Goldcorp here talking about an all-electric mine. They need equipment. They need heavy equipment to be battery operated, and then selling that around the world. Is it part of your plan to look at that?
